About Re-circulatory Aquaculture System:
- It is a technology where water is recycled and reused after mechanical and biological filtration and removal of suspended matter and metabolites.
- It is used for high-density culture of various species of fish, utilizing minimum land area and water.
- Key Features of Re-circulatory Aquaculture System:
- It is an intensive high density fish culture unlike other aquaculture production systems.
- It is also a closed-loop tank-based farming that recycles water after filtration.
- RAS filters and cleans the water in the tank, removing waste and keeping it safe for the fish to live in.
- It has automated set up of culture tanks with both mechanical and biological filtration units, and effectively prevents the entry of pathogens from external sources.
- It requires the minimal interventions to assess the culture, water and disease monitoring, which allows for improved biosecurity.
- It can be set up indoors or in areas without natural water sources, allowing fish to be raised closer to cities and where demand is high.
